My invention relates to improvement in furniture construction.

Some of the more important advantages of the device, which is thesubject of my invention are: (1) My invention provides means forassembling chairs and other furniture items quickly from their componentparts. (2) Furniture items embodying my invention can be quicklydismantled for shipment or storage thus greatly reducing shipping andstorage costs. (3) Furniture items embodying my invention can bemanufactured readily from plastic materials and plywood. (4) And,furniture items embodying my invention are strong, sturdy, andeconomical in construction.

One form of the invention is illustrated in the accompanying drawing, inwhich:

Figure 1 is a side View of a chair constructed in a manner embodying myinvention.

Figure 2 is an enlarged sectional view of Fig. 1 taken through 2-2 toshow in detail the single connecting means which is an important featureof my invention.

Figure 3 is a View of the back and sides of the chair together with asectional view of the seat and part of the stand to show the relation ofthese various pieces to each other.

Figure 4 is an enlarged sectional view of Fig. 3 taken through 4-4 toshow in detail additional important interlocking features of myinvention.

Figure 5 is a collective detail perspective view of the chair showingthe parts in position to be assembled.

In describing my invention in greater detail, reference will be had tothe accompanying drawing wherein like characters denote like orcorresponding parts throughout the several views.

Referring to the drawings, the chair, which is of a knock-down type,comprises a base or pedestal formed from interengaged member 5 and 6,which base supports a removable back member I and side members 8 and 9interengaging with the upper end of the back member 1, and detachablyanchored at their lower ends to the seat II] at opposite sides thereof.The lower ends of the side members are held in anchored relation byremovable pins II and I2, and the whole assembly is locked together inchair form by a single bolt [3 extending downwardly through the seat andthrough a washer l4 held in the upper end of the pedestal, and withwhich a nut l5, on the bolt, cooperates for rigidly holding the partstogether.

The lower ends of the arms 8 and 9 extend downwardly through openings I6and I! in opposite sides of the seat I0 and terminate below 4 Claims.(Cl. 155134) the seat. The lower ends of the arms 8 and 9 are providedwith spaced apertures for the reception of transverse removable pins IIand I2, hence it will be seen that the lower ends of the arms arerigidly anchored to the rear portion of the seat at opposite sidesthereof, hence will rigidly support the upper end of the back I. Therear side of seat It] is recessed as shown in Figure 5 to form oppositeshoulders 18 and IQ for the reception of the lower end of the back I andthe notches (a in opposite sides of the lower end of the back, thereforeit will be seen there is a positive detachable interlocking of the lowerend of the back and rear of the seat. The upper end of the back I isprovided with recesses 20 and 2| for the reception of the upperbifurcated ends 22 and 23 of the arms 8 and 9. Pins H and 12 passthrough the spaced apertures 24 and 25 in the portions of the sidemembers 8 and 9 projecting below the seat It), as clearly shown inFigure 1. Extending in opposite directions from the center of the underside of the seat ID are channels 26, and extending in cross relationthereto and in a direction from the front to the rear of the under sideof the seat are channels 21 for the reception of the upper edges of thecrossed interengaged pedestal members 5 and. 6. The pedestal member 5,which is in vertical longitudinal relation in the structure, is providedwith a rearwardly elongated arm 210. having spaced notches 28 and 29therein, and which notches are in alinement with the apertures 2d and 25of side members 8 and 9, so that when the locking pins II and [2 areplaced in position, or inserted from one side of the structure to theother, they will be received in the notches 28 and 29. Pins H and I2 arepreferably provided with notches 38 and 3| in their under sides adaptedto spring into interengagement with the bottom of the notches 28 and 29for preventing easy longitudinal displacement of the pins.

Substantially centrally of the seat I8, an aperture 32 is provided forthe reception of the bolt l3. Bolt l3 extends downwardly into the upperend of the pedestal and terminates below the entrance passage 33 in theupper end of the pedestal and below the inwardly extending arms 34, 35,36 and 31 of the crossed pedestal members. Disposed on the bolt 13 isthe washer M, which washer engages the under sides of the arms 34 to 3'!inclusive, and the washer is held in close binding engagement with theunder side of said arms by the nut [5. It will be seen that when the nutI5 is tightened the seat In is securely clamped on the upper edges ofthe crossed members 5 and 6, and said upper edges are forced intointerengagement with the seat and into the channels in the under side ofthe seat. The outer end of the elongated arm 21a terminates in anupwardly extending arm 29, which arm engages the rear lower side of theback 1, after the rear end of the arm 2| is in the recess 40 in thelower end of the back, hence it will be seen that the lower end of theback is securely locked between the shoulders l8 and [9 against outwardmovement. It will be noted that the upper side of the rearwardlyextending arm 21a, adjacent the member 39, engages the upper end of therecess 40.

From the above it will be seen that a knockdown chair is provided whichis simple in con struction, and held together by a single bolt and twolocking pins. It will also be seen that the device can be cheaplymanufactured and sold.
